` ATENT MANUFACTURE OF CEMENT COFFINS.

SPECIFICATION forming part of Letters Patent No. 259,373, dated June 13, 1882.

Application filed July 6, 1881. (No model.)

To all whom it may concern Be it known that I, TAYLOR DANIELS, a citizen ot the United States, residing at Ghicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in the Manufacture of Cofiins from Marble Cement; and I hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, ot' which--V Figure lis a perspective view of a coffin with a portion of the side broken away, showing an internal strengthening-frame over which the coffin is molded Fig. 2, a transverse section of the same; Figs. 3, 4, 5, and 6, detail views, and Fig. 7 a perspective view of the mold.

My invention relates to the manner in which I mold the coffin, withoutthe use of acore, over a metallic frame having a bottoni adapted to be attached to the sides of the frame after the molding has .been completed withrespect to the latter. Any form of frame with such a bottom may be employed 5 but the form shown in the drawings is suggested as strong and convenient. y

In the drawings, A is the body of the coffin, B the lid, and C an embedded strengthening: frame, comprising corrugated metal plates o, having perforations n, and metallic strips or bars t, passing through slots in the corrugations transversely ot' the said plates. The strips t of the sides of the cotlin are bolted to the strips t of the bottom, as shown at s. In addition to I[he transverse strips t, I sometimes employ, especially in the bottom, (although the same 'may be employed with advantage also in the lid and sides,) two or more longitudinal strips, l', lying in the channels of the corrugations, and likewise bolted to the strips t, as shown at s. The ends are provided with the frame in the same manner as the sides. In order to mold the coflin, I provide the mold D with risers q and q', projecting inward from both the upper and lower edges, for the purpose of forming, while in process of molding, a gage for the thickness of cement on the interior side ot' the frame G.

To form the cotn the sides and ends of the mold are all laid down to the position of the sidcp in Fig. 7. A layer of cement is then laid upon the face of the mold of such thickness as to fall below the tops ofthe risers, and the sides and ends of the metal frame pressed into this layer in their proper places. After this has been given a little time to set a layer of the cement is placed over the frame and is leveled off even with the tops of the risers to form the inner walls of the coffin. This in turn having also been given a little time to set, the sides and ends. of the mold are all raised Vup and secured together by means of the clamps o. The bottom E is then inserted and bolted in place to the ends ot' the strips t, provided these are employed. Otherwise any other suitable means of fastening may be adopted. A layer of the cement ot' sufficient thickness is then placed on its'interior surface and the whole allowed to harden, when the con-body will be complete with the exception of the exterior of the bottom, to iinish which the coffin is removed from the mold and inverted.

The above description relates to the molding of the coffin right side up, in which case the exterior of the bottoni is finished last. It' preferred,.however, the cofiin may be molded in the same manner in an inverted position, in which case the interior ot' the bottom is the last-nished. The only difference required in the construction of the mold for the latter method is that the risers adjacent to the bottom should in this case bemade removable,in order that they may be taken oli when the bottom is tobe setin and bolted in place. Of course, if formed in the latter way, the cross-strips ot' the bottom will be bolted to the under side oi' the cross-strips ot' the sides, as shown in Fig. 2, whereas if molded in the way first named they will be bolted to the upperside ofthe same. One of the chief advantages ot' iormingthe cofn in this manner and setting the bottom in last is thatit avoids the use of a core, which is always liable to swell and check the material, besidesbein g always dilicult to remove. Another object of doing away with the core is that the cement, not having to be poured, may in that way be applied in a much thicker consistency than if a Core is used; and it is a Well-known fact that the stiffer the materialis Worked the stron ger it becomes when hardened.

The lid is formed in a separate mold in the same manner as the sides.

What I claim as new7 and desire to secure by Letters Patent, is-

l. In an embedded frame of a molded cotn, the bottom E, formed of corrugated and perforated sheet metal7 having' cross-strips t passing through slots in said eorrugations, and longitudinal strips i' lying in the channels of said corrugations and bolted to the said crossstrips, substantially as described.

2. The method herein described of molding a cement coffin without the use of a core, which consists in forming the sides and ends over a metal frame with the walls of the mold laid down, placing the said walls together and locking them, inserting and securing to the 2o TAYLOR E. DANIELS.
